A magnetic pump with self-cooling function

Abstract

The present invention relates to the technical field of magnetic pumps, and specifically discloses a magnetic pump with a self-cooling function, comprising a pump body, wherein the outer wall of the pump body is connected to heat dissipation fins, and a water circulation cooling module is arranged on the outer side of the heat dissipation fins. The water circulation cooling module comprises a cover shell, a cooling box, a main pipe and a return pipe fitting. The cover shell is sleeved and connected to the outer side of the pump body, and the heat dissipation fins are located in the cover shell. The cooling box is arranged at one end of the pump body, the main pipe is connected to the side opposite to the cooling box and the pump body, and the return pipe fitting is symmetrically connected to both sides of the outer wall of the main pipe. By arranging the water circulation cooling module on the outer side of the pump body and making the heat dissipation fins located in the water circulation cooling module, the power generated by the rotation of the blades driven by the rotating shaft causes the cooling water in the water circulation cooling module to flow, thereby ensuring the water circulation effect. When the water circulates, the water liquid not only quickly takes out the heat from the outer surface of the heat dissipation fins, but also dissipates heat to the pump body. At the same time, the water circulation cooling module can be automatically turned on when the temperature of the pump body is high.

Description

Technical Field

[0001] The invention belongs to the technical field of magnetic pumps, and in particular relates to a magnetic pump with a self-cooling function. Background Art

[0002] The magnetic pump is mainly composed of several parts such as a pump head, a magnetic transmission (magnetic cylinder), a motor, and a base. In the prior art, the patent with the announcement number CN218439914U discloses a magnetic pump with good heat dissipation effect. For the cooling and heat dissipation of the magnetic pump, the heat in the magnetic pump is extracted by the heat dissipation fins. However, the heat dissipation fins will discharge the absorbed heat in two ways. One is to dissipate the heat into the air by contact with the air, and the other is to connect auxiliary heat dissipation plates at the ends of some heat dissipation fins to speed up the heat extraction in the heat dissipation fins. However, in these two ways, the first way only relies on the heat dissipation performance of the heat dissipation fins themselves, while in the second way, the contact area between the auxiliary heat dissipation plate and the heat dissipation fins is small and is only concentrated on the ends of the heat dissipation fins. The heat conduction effect is limited, and there is a technical problem of insufficient heat conduction effect. If the heat in the heat dissipation fins is not discharged in time, the heat dissipation and cooling effect of the heat dissipation fins on the magnetic pump will be reduced.

[0003] At the same time, in a self-cooling magnetic pump with the announcement number CN216342850U, the water used for cooling is the liquid pumped by the pump body, so the spiral cooling water channel in the pump body is connected to the outside world. When external impurities enter the spiral cooling water channel with the water, it will cause blockage of the spiral cooling water channel, thereby interfering with the cooling effect of the water on the pump body, and the airflow of the motor cooling fan is used to further dissipate heat to the external magnet and inner rotor, and the airflow will carry the heat generated by the motor operation, thereby reducing the heat dissipation effect of the external magnet and inner rotor. Summary of the Invention

[0004] The object of the present invention is to provide a magnetic pump with a self-cooling function to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] The heat dissipation device is connected to the outer wall of the pump body by the heat dissipation device, and the heat dissipation device is connected to the outer wall of the pump body by the heat dissipation device. The heat dissipation device is connected to the outer wall of the pump body by the heat dissipation device.

[0007] Preferably, the water circulation cooling module also includes a hollow ring and a first-level connecting pipe. The hollow ring is arranged between the cover and the cooling box, and the hollow ring is connected to the pump body. The first-level connecting pipe is connected to one side of the hollow ring in a circumferential array, and the end of the first-level connecting pipe away from the hollow ring is connected to the cover. The cooling water in the cover is guided into the hollow ring through the first-level connecting pipe, and the paddles in the hollow ring provide power for the circulation of the cooling water.

[0008] Preferably, the water circulation cooling module also includes a driving motor, a rotating shaft, a connecting rod, an inner groove opening, a rotating plate and blades. The driving motor is connected to the middle part of one side of the pump body through a positioning bolt, one end of the rotating shaft is connected to the output end of the driving motor, the circumferential array of connecting rods is connected to the outer wall of the rotating shaft, the inner groove opening is opened on the inner side of the hollow ring, the rotating plate is arranged in the inner groove opening, and the rotating plate and the hollow ring are slidably fitted, the end of the connecting rod away from the rotating shaft is connected to the inner wall of the rotating plate, the circumferential array of blades is connected to the outer wall of the rotating plate, and the blades are slidably fitted with the hollow ring, the driving motor drives the rotating shaft to rotate, and the rotating shaft drives the blades to rotate, thereby guiding the water in the cover shell into the hollow ring through the first-level connecting pipe.

[0009] Preferably, the water circulation cooling module also includes a hollow column and a secondary connecting pipe fitting. The hollow column is connected to the middle part of the side of the cooling box close to the pump body, and a gap is left between the hollow column and the rotating shaft. The circumferential array of the secondary connecting pipe fitting is connected to the outer wall of the hollow column, and the end of the secondary connecting pipe fitting away from the hollow column is connected to the hollow ring. The cooling water in the hollow ring is guided into the cooling box through the hollow column and the secondary connecting pipe fitting.

[0010] Preferably, the water circulation cooling module also includes a plurality of mounting plates, which are symmetrically connected to the top and bottom of the cooling box, and the plurality of mounting plates are connected to the hollow ring through positioning bolts to connect and fix the cooling box and the hollow ring.

[0011] Preferably, the monitoring module also includes an airbag and a lifting plate. The airbag and the lifting plate are both arranged in the top cover, and the bottom end of the airbag is connected to the mesh plate, and the top end of the airbag is connected to the lifting plate. The lifting plate is slidably fitted around the inner wall of the top cover. The airbag is filled with water, and the lifting plate rises or falls through the expansion or contraction of the airbag.

[0012] Preferably, stabilizing grooves are symmetrically opened on the inner wall of the top cover, and stabilizing plates are slidably fitted in the stabilizing grooves, and the stabilizing plates are symmetrically connected to both sides of the jacking plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: when the present invention is in use, a water circulation cooling module is arranged on the outside of the pump body, and the heat dissipation fins are placed in the water circulation cooling module. The power generated by the rotation of the blades driven by the rotating shaft causes the cooling water in the water circulation cooling module to flow, thereby ensuring the water circulation effect. When the water circulates, the water not only quickly takes out the heat from the outer surface of the heat dissipation fins, but also dissipates heat to the pump body. When the temperature of the pump body itself is low, the water circulation cooling module is not turned on, reducing energy consumption, and heat is only dissipated through the temperature of the cooling water itself in the cover. When the temperature is high, the temperature of the pump body and the heat dissipation fins will increase the temperature of the cooling water, cooling The temperature of the water is conducted to the water in the airbag through the mesh plate. The vaporized water increases the air pressure inside the airbag and expands it, thereby lifting the lifting plate. When the lifting plate contacts the contact switch, the water circulation cooling module starts to operate. As the water temperature drops, the vaporized water condenses and merges into the water in the airbag, causing the air pressure inside the airbag to drop and shrink. The lifting plate lacks the force to push up and drops, and separates from the contact switch. The water circulation cooling module no longer operates, allowing the magnetic pump to automatically cool itself when its own heat is high, and automatically stop the operation of the water circulation cooling module when its own heat is low, thereby reducing energy consumption.

[0031] Working principle: The heat generated by the pump body 1 during operation is absorbed and discharged through the heat dissipation fins 2, thereby achieving a heat dissipation and cooling effect on the pump body 1. When the pump body 1 itself generates a lot of heat and the heat dissipation fins 2 cannot discharge the heat in time, the heat of the pump body 1 itself and the heat discharged by the heat dissipation fins 2 will quickly increase the temperature of the cooling water. The temperature of the cooling water is transmitted to the water in the air bag 44 through the mesh plate 42. The water absorbs heat and vaporizes. The vaporized water increases the internal air pressure of the air bag 44 and expands, thereby lifting the jacking plate 45. When the jacking plate 45 rises and contacts the contact switch 49, the contact switch 49 is triggered, and the contact switch 49 transmits a signal to the peripheral terminal. The peripheral terminal receives the signal and controls the drive motor 37 to turn on. The drive motor 37 drives the rotating shaft 38 to rotate, and the rotating shaft 38 drives the blade 312 to rotate, thereby guiding the water in the cover 31 to the hollow ring 3 through the first-level connecting pipe 36. 5, providing power for the circulation of water. The water enters the cover 31 again through the secondary connecting pipe 314, the hollow column 313, the cooling box 32, the main pipe 33, and the return pipe 34. The water is cooled when passing through the cooling box 32. When the water enters the cover 31 again, the temperature of the water in the cover 31 will be reduced. As the water temperature decreases, the vaporized water in the air bag 44 condenses and merges into the water in the air bag 44, causing the internal air pressure of the air bag 44 to decrease and retract. The lifting plate 45 lacks the upward force and falls, and is separated from the contact switch 49. The contact switch 49 transmits a signal to the external terminal. The external terminal receives the signal and controls the drive motor 37 to turn off. The water circulation cooling module 3 no longer operates, so that the magnetic pump can automatically cool itself when its own heat is high, and automatically stop the water circulation cooling module 3 when its own heat is low, thereby reducing energy consumption.
